CAP-lRON FOR POLES FOR SUSPENDING ELECTRIC LIGHTS.

SPEQIPIC'ATION forming part of Letters Patent No. 339,371, dated April 6, 1886.

Application filed September 8, 1885. Serial No. 176,531.

To all whom it may concern.-

Be it known that I, THOMAS H. BRADY, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Cap-Irons for Poles for suspending Electric Lights, of which the following is a specification.

In the accompanying drawings, Figurelisa perspective view of a pole cap-iron lever for suspending an electric light, and mechanism for operating said lever. Fig. 2 is a plan view of my cap-iron for said pole. Fig. 3 is a rear elevation thereof, and Fig. 4isaside elevation of the same.

A designates a pole to be set by the roadside, and provided at the top with a cap, B, having'lugs a,within which to pivot the lever C. The long end of this lever is provided at its extremity with a crossarm, I), having hooks in, by which to suspend the lamp so that it may swing thereon and always maintain an upright position, whether the lever O is hori zontal or otherwise. The cross-arm curves upward and cutwarchsomething like the horns of an ox,whereby when the lever Ois horizontal in position to suspend the lamp over the street, as shown, the hood of the lamp comes under the end of the lever O and renders it impossible to n nhook the lamp from the arms. The shorter end of the lever O is provided with a downwardly-extending arm having an eye, 0, to receive the rod (1. To the lower end of this rod I attach a cord, f, preferably of twisted wire.

To the body of the pole A, I firmly secure the frame E, upon which frame is mounted the shaft g, having a thread or worm thereon, and the shaft 7:, bearing the worm-gear k and the drum in. One end of the cord f is fastened to this drum. The end of the shaft 5/ is squared or otherwise formed for the ready attachment of a crank thereto.

Upon the cap B, at the side opposite the (No model.)

pivotal lugs a, I form two upwardly-projecting lugs, s, between which the main rod or beam of the lever G enters when said lever is brought into a horizontal position, as shown in Fig. 1. These lugs s steady the lever C and prevent it from swinging around laterally under the action of the wind. I also provide the cap-iron with arms a, for attaching the ordinary insulators and wires.

The body of the cap B is in tubular form, like a large ferrule or socket, and is designed to receive the end of the pole to which it is secured. The lugs s have an open space between them, so that they will be less likely to become filled with snow and ice than would a notch formed in the upper side of a single arm.

The weight of the lever and its appendages is sustained wholly by its pivotand the operating mechanism at the middle of the pole.

The cap is simple in construction, and can be cast with its several parts all in one piece,

and when cast it furnishes a cheap, convenient, and efficient means for attaching the other parts.

I have herein shown and described the swinging lever and its operating mechanism only for the purpose of showing the use of the cap B. Said lever and mechanism, although of my invention,-are not herein claimed, but are made the subject of another application of even date herewith.

I claim as my invention The herein-described cap-iron for poles for suspending electric lights, the same consisting of the tubular body, the pivotal lugs a, the insulator-arms a n, and the upwardly-projecting lugs s s opposite the pivotal lugs, all formed integral, substantially as described and for the purpose specified.
